Oh thank God i found this.... Ive been having this issue with the pets for MONTHS. this ties into the issue with the walking where the Dog walks away from your sim while off leash. Dogs will disappear, appearing to move slowly somewhere hidden off map and itll lead to other sims in the household getting stuck on the dog, However, because you cant see the dog in order to click on it, it wont let you reset the dog. which would immediately resolve the issue. instead, you have to go to manage worlds , exit and switch households, come back to the previous household and hope it force reset them. This bug is unbelievably irksome itll lead to kids almost going hungry or stink because everyone in the households interactions are queued up behind the missing dog.
